If there is no force, or other exchange services aren't banned or made inaccessible, I think I would stick with the ones I'm using right now, such as Binance, Bitget, and OKX. The reason is pretty simple, I have been using those exchanges for years, and have never faced any issues till this date, whether it's about trading, deposits and withdrawals, P2P trades, or anything in general, I have always been satisfied with the services even though they are centralized and I have provided them with my personal documents.
That being said, if the government launches its own exchange and then bans or blocks our access to other platforms only so that we use their exchange, in that case, I might or might not use it. If I feel that it is the easiest way to get things done and the user experience is good, which means there are no problems users facing or any other issues, I might use it, but if I can still find some other alternative, I might go for that instead.
